Internet gaming addiction (IGA), as a subtype of internet addiction disorder, is rapidly becoming a prevalent mental health concern around the world. The neurobiological underpinnings of IGA should be studied to unravel the potential heterogeneity of IGA. This study investigated the brain functions in IGA patients with resting-state fMRI.
Fifteen IGA subjects and fourteen healthy controls participated in this study. Regional homogeneity (ReHo) measures were used to detect the abnormal functional integrations.
Comparing to the healthy controls, IGA subjects show enhanced ReHo in brainstem, inferior parietal lobule, left posterior cerebellum, and left middle frontal gyrus. All of these regions are thought related with sensory-motor coordination. In addition, IGA subjects show decreased ReHo in temporal, occipital and parietal brain regions. These regions are thought responsible for visual and auditory functions.
Our results suggest that long-time online game playing enhanced the brain synchronization in sensory-motor coordination related brain regions and decreased the excitability in visual and auditory related brain regions.
网络成瘾(IGA)作为网络成瘾障碍的一个亚型,正在迅速成为全球普遍存在的心理健康问题。应该研究 IGA 的神经生物学基础,以揭示 IGA 的潜在异质性。本研究使用静息态 fMRI 研究了 IGA 患者的大脑功能。
15 名 IGA 患者和 14 名健康对照者参与了这项研究。采用局部一致性(ReHo)测量来检测异常的功能整合。
与健康对照组相比,IGA 患者的脑干、顶下小叶、左小脑后叶和左额中回的 ReHo 增强。所有这些区域都被认为与感觉运动协调有关。此外,IGA 患者的颞叶、枕叶和顶叶脑区的 ReHo 降低。这些区域负责视觉和听觉功能。
我们的结果表明,长时间的网络游戏会增强与感觉运动协调相关的脑区的大脑同步性,并降低与视觉和听觉相关的脑区的兴奋性。
